Embodiment Construction

[0010] Below in conjunction with accompanying drawing, technical solution of the present invention is described in further detail: as figure 1 As shown in the figure, a self-cleaning grate used in a garbage pneumatic conveying system includes an air inlet (1), a housing (2), a heterogeneous screen (3) and an air outlet (4). The self-cleaning grid is placed behind the cyclone separator of the garbage pneumatic conveying system to achieve two-stage gas-solid separation.

[0011] The air inlet (1) and the air outlet (4) are fixed on the housing (2), and the axes of the air inlet (1) and the air outlet (4) are not on a straight line, the air inlet (1), the air outlet (4) The axial distance is greater than the maximum diameter of the air inlet (1) or the air outlet (4). The screen (3) is located inside the housing (2) and has a non-planar structure. The screen (3) is located at the air inlet (1) and the air outlet (4) respectively in relation to the air inlet (1) and the air outle...

Abstract

The invention relates to a self-cleaning grille for a pneumatic garbage conveying system. The self-cleaning grille comprises an air inlet, a shell body, a special-shaped screen mesh and an air outlet.The grille is arranged behind a cyclone separator. Air flows inside from the air inlet and flows out from the air outlet, and while the air passes through the inner special-shaped screen mesh, air-solid separation and self-cleaning are realized. Compared with a traditional grille, the self-cleaning grille solves the problems of liable jamming and short cleaning cycle.

Description

technical field [0001] The invention relates to a self-cleaning grate used in a garbage pneumatic conveying system. Background technique [0002] The garbage pneumatic conveying system is a kind of pneumatic conveying system that uses garbage as the material. Through high-speed airflow, the garbage in the pipeline is transported to the collection station, and the gas-solid separation is carried out in the collection station. The garbage pneumatic conveying system performs primary gas-solid separation through a cyclone separator to separate larger solids, and then performs secondary gas-solid separation through traditional grids or screens to separate smaller solid particles. Traditional grids have problems such as easy clogging and short cleaning cycles during use. Contents of the invention [0003] In order to improve the problems of easy blockage and short cleaning cycle in the traditional grid structure, the present invention provides a new type of self-cleaning grid f...
